Basically, the act of the Dutch Oven, but gone wrong. Instead of the other persons head being held underneath the covers, you find your own head underneath the covers, forcing you to inhale your own gasses.

Man1: Dude, did you give your girlfriend that Dutch Oven, as you told me you would?

Man2: Yeah, I tried, but she managed to turn it into a dutch oven suicide and trapped me underneath the blankets after I farted, I vomited for an hour.
